Frequently Asked Questions

What is the best way to increase repeat purchases?

Capture every buyer to email or SMS, then send timely, relevant messages: welcome flows, post-purchase education, and win-back offers. Klaviyo and ConvertKit automate this; loyalty features and subscriptions deepen the relationship.

How do I measure retention?

Watch repeat purchase rate, customer lifetime value, and churn for subscriptions. Pair them with engagement data from Fathom or Google Analytics to see which segments come back and why.

Is email still worth it for ecommerce?

Yes — email and SMS consistently deliver the highest ROI of any retention channel because you own the audience. A well-run flow can outperform paid social for repeat revenue at a fraction of the cost.
